High Precision CNC Roll Lathe

●The CK8450H CNC roll lathe bed adopts a Siemens 828D CNC system and Siemens servo motor drive, ensuring good control performance. The 828D system has the performance of program automatic simulation cutting, fault self-diagnosis, etc., to ensure performance stability in the cutting process.
●CK8450H CNC roll lathe bed adopts a 2+3 heavy-duty linear rolling guide structure, that is, two rectangular guide rails arranged horizontally on the bed provide the movement and positioning of the tailstock. Two heavy-duty linear rolling guide rails arranged in parallel provide the bed saddle movement and positioning, and a linear rolling guide rail is set on the vertical surface of the front side of the bed as an auxiliary support for the bed saddle to ensure that the bed saddle and tool rest not only have good load-bearing rigidity but also have excellent sensitivity and dynamic accuracy. 
●The lathe spindle adopts a two-point support form, reasonable bearing configuration, and span design, and the spindle has high rigidity and load-bearing capacity. The optimized and designed transmission system adopts high-frequency quenching and grinding 6-level precision gear transmission so that the spindle box has the characteristics of low noise, high transmission precision, and large output torque.
The spindle transmission adopts a stepless speed regulation scheme of 2-speed gear shifting & variable frequency speed motor drive, which enables the machine tool spindle to have a wide and highly dynamic speed regulation range of 3~350rpm. The 2-speed gear shifting ensures the constant torque of the spindle at different speeds and improves cutting efficiency.
